Construct a triangle `A B C` in which `A B=5. 8 c m ,\ B C+C A=8. 4\ c m\ a n d\ /_B=60^0`

Explanation

To construct triangle ABC with the given conditions \( AB = 5.8 \, \text{cm} \), \( BC + CA = 8.4 \, \text{cm} \), and \( \angle B = 60^\circ \), follow these steps:

### Step-by-Step Solution:

1. **Draw the Base**:
- Draw a line segment \( AB \) measuring \( 5.8 \, \text{cm} \).
- Label the endpoints as \( A \) and \( B \).
